Nimby, you're trying so hard on the details that you are missing the broad point ie that there is probably not enough room. Changing my eyeball of 1500' to 11th into 1375' from 9th is not significant (@2%=2.5') so is changing my round figure 2% to 1.93% (1'). Ditto moving the 7 line from an approach down Hudson Blvd to a platform under 11th. That 0.4% grade is from mid station to the last crossovers before the tunnel, the bulk of the grade is the 1.93%.My first post already said that the Empire line passes over the North River tunnels and under WSY's subgrade, I saw a picture of it a trade magazine when it was being built. Google Earth and ARC/Gateway plans show that the turn north is roughly under 11th Ave. Room inside or outside of the existing curve seems the only possibility but even that is doubtful. Bill |
